Abstract

The present invention is related to an aqueous composition comprising an alkalizing agent and an aqueous emulsion of a silicone copolymer. The inventors of the present invention have surprisingly found out that a composition comprising at least one alkalizing agent and an aqueous emulsion of divinyldimethicone/dimethicone copolymer with an internal phase viscosity of more than 1×10 8 mm 2 /s measured at 0.01 Hz and at about 25° C. colors and/or permanently shapes hair excellently and improves hair shine, combability and manageability and especially hair treated with such composition has less flyaway. Additionally it has been observed that hair colored and/or permanently shaped more homogeneously from root to tips. The subject of the present invention is an aqueous composition for human hair comprising at least one alkalizing agent and an aqueous emulsion of divinyldimethicone/dimethicone copolymer with an internal phase viscosity of more than 1×10 8 mm 2 /s measured at 0.01 Hz and at about 25° C.
